Alert Details

A potentially more active weather pattern with more southerly winds through next weekend may lead to isolated corn earworm moth flights into portions of the corn-growing region. Low risks are in place overnight tonight into Wednesday morning especially from Kansas and southeast Nebraska into Iowa, Illinois, and Missouri as south to southwest winds blow north and encounter a frontal boundary near the I-80 corridor. Showers and storms may develop along this boundary and serve as potential drop-out areas. No risk is predicted for Wednesday night into Thursday, but Low risks are widespread across much of the corn-growing region (especially south of I-90 and I-94) for the extended period as multiple opportunities for showers/storms exist especially during the nighttime hours when southerly winds will be their strongest at moth flight level. Risks initially start in the Plains Thursday night but then spread east into the eastern Midwest by the end of the weekend.
